"The past year was a challenge," she said. "Whether it be the record label disagreeing with me on single choices, or directors who could only create an idea of 'Gaga' or what I've 'done before' and not able to move forward.

"And there was also of course the incessant dragging of the most important single of my career in dead-beaten-horse-mud.

"Then there were all the personal moments. Betrayed by lifelong friends, mentors I've had for years suddenly taking advantage of me, and a massive struggle with my body image."

She continued: "I've grown and left most of these things behind, the monsters of fame are very real. But I wanted to thank you for bearing with me a little bit."
